Vibrotactile Coordinated Reset for the Treatment of Chronic Stroke

The Fugl-Meyer Assessment (FMA) is a stroke-specific, performance-based impairment index. It is designed to assess motor functioning, balance, sensation and joint functioning in patients with post-stroke hemiplegia. It is applied clinically and in research to determine disease severity, describe motor recovery, and to plan and assess treatment. The scale is comprised of five domains and there are 155 items in total. Scoring is based on direct observation of performance. Scale items are scored on the basis of ability to complete the item using a 3-point ordinal scale where 0=cannot perform, 1=performs partially and 2=performs fully. The total possible scale score is 226.

The Neuro quality of life upper extremity short form test measures the functionality of upper extremities. This is a self-report questionnaire that has a Likert scale from 1 to 5, with 5 indicating no difficulties and 1 indicating unable to do. Total possible points are out of 40, with a higher score indicating better upper extremity abilities.

The Barthel Index (BI) measures the extent to which somebody can function independently and has mobility in their activities of daily living (ADL) i.e. feeding, bathing, grooming, dressing, bowel control, bladder control, toileting, chair transfer, ambulation and stair climbing. Functional categories may be scored from 0 to 1, 0 to 2, or 0 to 3, depending on the item. Total scores range from 0 to 20, with lower scores indicating increased disability

The Action Research Arm Test (ARAT) is a 19 item observational measure used by physical therapists and other health care professionals to assess upper extremity performance (coordination, dexterity and functioning) in stroke recovery, brain injury and multiple sclerosis populations.Items comprising the ARAT are categorized into four subscales (grasp, grip, pinch and gross movement). Task performance is rated on a 4-point scale, ranging from 0 (no movement) to 3 (movement performed normally). Scores on the ARAT may range from 0-57 points, with a maximum score of 57 points indicating better performance.

This test is a measure walking ability with correlates to balance and fall risk. The patient is timed using a stopwatch and the patient is instructed to walk as quickly as possible for 3 meters. The test is scored as such: ≤ 10 seconds = normal ≤ 20 seconds = good mobility, can go out alone, mobile without gait aid ≤ 30 seconds = problems, cannot go outside alone, requires gait aid * A score of ≥ 14 seconds has been shown to indicate high risk of falls

The Neuro quality of life lower extremity short form test measures the functionality of upper extremities. This is a self-report questionnaire that has a Likert scale from 1 to 5, with 5 indicating no difficulties and 1 indicating unable to do. Total possible points are out of 40, with a higher score indicating better lower extremity abilities.

Patients receive vibratory stimuli on a finger and indicate when stimuli are felt by pressing a button.

Patients receive vibratory stimuli on two fingers either simultaneously or at different times and indicate the perceived timing by pressing a button.
